Abstract
Description
Die Erfindung betrifft eine Fahrzeugbeleuchtungseinrichtung, insbesondere eine Fahrzeug-Heckleuchte mit wenigstens einem LED-Leuchtmodul.The The invention relates to a vehicle lighting device, in particular a vehicle tail light with at least one LED light module.
Fahrzeugleuchten,
insbesondere Fahrzeug-Heckleuchten, die anstelle von Glühlampen oder
Quarzlampen Leuchtdioden (LED: light emitting diode) als Leuchtmittel
verwenden, sind bekannt. Als Beispiele seien die
LED-Leuchten, ebenso Kaltkathodenleuchten, setzen mehr elektrische Energie in Licht um als konventionelle Glühlampen. Während letztere bis zu 99% elektrische Energie in Wärme umwandeln, werden bei den erstgenannten modernen Lichtquellen nur 1% bis zu 10% in Wärme umgewandelt. Dadurch entsteht auch deutlich weniger Strahlungswärme als bei der Verwendung konventioneller Glühlampen, so dass bei niedrigen Temperaturen die Gefahr der Bildung von Tau und bei sehr tiefen Temperaturen gar von Eis auf der Innenseite der kalten Leuchtenabdeckscheibe besteht, bedingt durch die Kondensation von im Innern der Fahrzeugleuchte in der Luft befindlichem Wasserdampf. Bei Schneefall oder Luftfeuchtigkeit in der Außenluft in Verbindung mit Vereisungsbedingungen wird die Außenfläche der Leuchtenabdeckscheibe ebenfalls. nicht mehr abgetaut, sondern schneit ein oder vereist, so dass die Funktion der Scheinwerter nicht mehr sichergestellt ist. Dieses ist verbunden mit einer erheblichen Reduzierung der Leuchtkraft der Fahrzeugleuchte. insbesondere bei Schneefahrt sind LED-Leuchten schlecht oder sogar überhaupt nicht sichtbar.LED lights, as well cold cathode lamps, put more electrical energy in Light around as conventional light bulbs. While The latter convert up to 99% of electrical energy into heat first-mentioned modern light sources only 1% up to 10% converted into heat. This also results in significantly less radiant heat than at the use of conventional light bulbs, so at low Temperatures threaten the formation of dew and at very low temperatures Temperatures of ice on the inside of the cold Leuchtenabdeckscheibe exists, due to the condensation of inside the vehicle lamp airborne water vapor. In case of snowfall or humidity in the outside air in conjunction with icing conditions, the outer surface of the Luminaire cover also. no longer defrosted, but snowing one or iced, so that the function of the Scheinwerter no more is ensured. This is associated with a significant reduction of Luminosity of the vehicle lamp. especially when snow driving LED lights bad or even not visible at all.
Zur
Verhinderung dieser Erscheinung sind bekannte Fahrzeugleuchten mit
einer Heizvorrichtung zum Erzeugen vorgeheizter Luft in der Fahrzeugleuchte
ausgestattet, beispielsweise eine in der
Es ist Aufgabe der Erfindung, eine Fahrzeugleuchte nach dem Oberbegriff des Anspruchs 1, insbesondere im Fahrbetrieb, auf einfache Weise schnee- und eisfrei zu halten.It Object of the invention, a vehicle lamp according to the preamble of claim 1, in particular when driving, snowing in a simple manner. and ice-free.
Diese Aufgabe wird bei einer Fahrzeugleuchte nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnendes Merkmal gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is in a vehicle lamp according to the preamble of Claim 1 solved by its characterizing feature. advantageous Embodiments are listed in the subclaims.
Die Erfindung besteht darin, dass bei einer Fahrzeugleuchte, die ein Leuchtengehäuse mit einer Lichtaustrittsöffnung und mit einer diese überdeckenden Abdeckscheibe sowie mit einer in dessen Innenraum angeordneten lichtemittierenden Einrichtung aufweist, deren Licht durch die Abdeckscheibe abgestrahlt wird, die Abdeckscheibe mit im Fahrzeug durch die Motorwärme oder eine Klimaanlage erwärmter (Außen-)Luft beheizt wird. In Verbindung mit der Heizeinrichtung des Fahrzeugs wird die erwärmte Luft in den Fahrzeuginnenraum gedrückt, insbesondere durch ein Gebläse, so dass im Fahrzeuginnenraum ein leichter Überdruck gegenüber der Fahrzeugumgebung erzeugt wird bzw. herrscht. Mit diesem Überdruck wird die erwärmte Luft nach der Konditionierung des Fahrzeuginnenraumes ins Freie geleitet und auf dem Weg dorthin zur Erwärmung der Abdeckscheibe genutzt. Somit gelangt ohnehin beheizte Innenraum-Luft vor ihrem Abführen in die Fahrzeugumgebung zum nochmaligen Einsatz und beheizt die jeweilige Heckleuchte ohne heizungstechnischen Mehraufwand.The Invention is that in a vehicle lamp, a luminaire housing with a light exit opening and with one covering them Cover and with a light-emitting arranged in the interior Device having emitted light through the cover plate is, the cover with in the vehicle by the engine heat or an air conditioning heated (Outer) air is heated. In conjunction with the heater of the vehicle will the heated Air pressed into the vehicle interior, in particular by a Fan, so that in the vehicle interior a slight overpressure compared to the Vehicle environment is generated or prevails. With this overprint will the heated Air after the conditioning of the vehicle interior to the outside passed and used on the way there to heat the cover. Thus, in any case heated interior air passes before their removal into the vehicle environment for repeated use and heated the respective taillight without heating overhead.
Zweckmäßigerweise wird die Luft durch das Leuchtengehäuse und dabei an der Innenfläche der Abdeckscheibe vorbei geleitet. Die an dieser entlangstreichende Luft erwärmt die Abdeckscheibe über den Gefrierpunkt, so dass auf dieser befindlicher(s) Schnee und/oder Eis abgetaut wird. Im aufgeheizten Fahrzeugzustand stehen bei Außentemperaturen von 0/–10/–20°C mindestens 150 kg/h Luftmassenstrom mit einer Temperatur von 12/10/8°C zur Verfügung, gleichbedeutend mit 450/750/1050 W Heizleistung. Bei einem Kaltstart des Fahrzeugs steht schon nach wenigen Minuten erwärmte Luft zur Verfügung.Conveniently, the air passes through the luminaire housing and on the inner surface of the cover passed by. The air flowing along this heats the Cover disc over the Freezing point, so that on this (s) snow and / or Ice is thawed. In the heated vehicle state are at outdoor temperatures of 0 / -10 / -20 ° C at least 150 kg / h air mass flow with a temperature of 12/10/8 ° C available, equivalent with 450/750/1050 W heating capacity. At a cold start of the vehicle Warm air is available after just a few minutes.
Das Leuchtengehäuse sollte für die Luftdurchströmung wenigstens eine mit dem Fahrzeuginnenraum verbundene Lufteinlassöffnung und wenigstens eine Luftauslassöffnung aufweisen.The luminaire housing should for the air flow at least one air inlet opening connected to the vehicle interior and at least one air outlet opening exhibit.
